UPDATE: Thanks to some advice by doomlaser, I’ve fixed the problem with the screensaver. You can download the new version from the link at the bottom of the page.

Check out this screensaver. If you look at it in System Preferences it looks harmless enough. But when you actually run it, it shows a (fake) kernel panic.

This gave me the idea to make a BSOD (Blue Screen Of Death) screensaver. I’m sure that someone has already made one (if you know of a BSOD screensaver then tell me in the comments), but I decided to make it anyways just so I know how to, in case I ever want to make another screensaver.

Anyways, I made the screensaver myself. It was simple enough to make. I used Quartz Composer to make it (see this and this if you want to make your own screensaver with Quartz Composer).

To install, just download this file and put it in ~/library/Screen Savers.

Enjoy it, and go make fun of a Windows user!
